実験手順
After the calcination step 15, the impure lead monoxide and other impurities are subjected to an acid ammonium acetate leach at 21 to form a solution of lead acetate and an insoluble residue. The lead acetate solution is separated from the solids at 22. The solids, comprising an antimonial lead gangue is removed at 23 for smelting. The lead acetate solution is treated with ammonium hydroxide at 24 to precipitate lead hydroxide with the concurrent formation of an ammonium acetate solution. After separation of insoluble lead hydroxide from the solution at 25, the lead hydroxide is dehydrated by heating at 26 to form a pure PbO product at 27.
